A disturbing plot by three first grade pupils to bump off their classmate with packets of silica gel has been foiled at an Alaskan elementary school.

The plan to use the gel, which is in fact non-toxic, was reportedly brought to the attention of teachers at the Winterberry Charter School, Anchorage, by two concerned students privy to the shocking poison plot.

The trio, believed to be no older than 7-years-old, look set to escape criminal charges, however, with school psychologists being called in to see if the group were aware of the seriousness of their actions.

“The age is one of the things that is most surprising to people who were hearing about this. The kids are such a young age,” Anchorage School District spokesperson, Heidi Embley told Alaska Dispatch News.

“Without revealing any information as to what occurred during the investigation, there are a lot of conversations [needed] to get an understanding of what actually happened, how the students were feeling.”
